OAKLAND -- The Cowboys and Raiders are scoreless after the opening quarter at O.co Coliseum.

*It's never good when the quarterback has to tell the referees where to spot the ball. The replacement refs spotted the ball on the infield dirt, nowhere near the hash marks. Tony Romo had to tell the refs where the ball should be placed.

*Marcus Spears, getting work with the second team, picked up two tackles and almost recovered a fumble.

*Cole Bealsey is getting early snaps. He was the slot receiver on the first three-receiver set and the Cowboys threw a pass to him but he was covered well by Michael Huff.

*Romo faced pressure on the second offensive possession. He avoided some pressure to get a pass to Jason Witten, but it led to a two-yard loss. The next play, Romo was trying to set up a screen pass to DeMarco Murray, but nose tackle Tommy Kelly slipped past David Arkin for the sack.

*The Cowboys started the first two defensive series using Dan Connor, Sean Lee and Bruce Carter at inside linebacker. When the Cowboys went with the second unit, Barry Church remained as the safety.

*The Cowboys had three special team penalties, allowing the Raiders' offense to stay on the field. Fullback Jamize Olawale ran into the punter, Kevin Ogletree was called for holding and Teddy Williams was offsides. Bad plays for three guys looking for roster spots.

*I didn't like Dez Bryant playing tonight, but he made a 24-yard reception on the first pass play of the game. Bryant looked like he had a bounce in his step and seemed mostly recovered from his hamstring injury.

*Gerald Sensabaugh did a nice job of getting the first turnover of the preseason. He moved over from center field to help Orlando Scandrick intercept a Carson Palmer pass.
